METAL GATE.

" SPECIFICATION forming part of Letters Peten-t No. 673,192, datedApi-i1 so, 1901.

Applicant nea June 28,1990. seria No. 21,892. (No modera in Metal'Gates,of which the following is a` specification.

My invention relates to foldingiron gates for use on railway-cars,boats, elevators, &c. These gates are sometimes made of the lazytongspattern and sometimes of parallel bars connected by lazy-ton gs bars.Heretofore in making such gates it has been usual to employ flat bars ofmetal placed face-.to face and pivoted together. These gates when closedoccupy considerable rooln, because ,theadjacent meeting edges of thebars simply come together; and the object of my invention is to lessenthe space occupied and to be able to compactly close the gate and at thesame time retain the strength and effectiveness of the gate.

In carrying out my invention I employ bars each having two parallellongitudinal ribs upon one surface at either side of the center of thebar, and the respective bars forming the gate are connected in alternateoppositelyplaced pairs, so that when closed the adjacent meeting edgesoverlap. These bars may be connected directly together in the wellknownlazy-tongs form, or these bars may be placed vertical and parallel withone another and connected by a lazytongs system of smaller intermediatebars.

In the drawings, Figures l and 2 are elevations representing forms ofgates embodying my improvement. the form of gate shown in Fig. 1 asclosed. Fig. 1 is a sectional plan at a; of Fig. l in larger size, andFig. 5 is a sectional plan at y y, Fig. 3, in still larger size, showingthe gate closed and the bars overlapping. Fig. 6 is an elevation of theform of gateshown in Fig. 2 as closed. Fig. 7 is a partial plan view, inlarger size, of the parts shown in Fig. 2; and Fig. 8 is a sectionalplan at z z of Fig. 6 in larger size with the gate closed and therespective bars overlapping.

The main or principal bars a, composing the forms of gates, are eachprovided with two parallel longitudinal ribs b b upon one Fig. 3 is anelevation of` `surface at either side of the center of the bar andspaced at substantially the same distances from the edges that they areapart. These bars are to be arranged in alternate oppositely-placedpairs-that is to say, two connected bars will be placed with their fiatsurfaces opposite or adjacent and the next pair of bars with theirribbed surfaces opposite or adjacent-and the bars are preferablyconnected together by pivot-pins c, the heads of which where the flatfaces of the bars come adjacent are received in the grooves formedbetween the parallel longitudinal ribs.

In Figs. l, 3, 4, and 5 the form of gate shown comprises verticalparallel bars a, in pairs, with a system of lazy-tongs bars d e betweenand connecting the vertical bars a and which systems of bars d e closetogether, spreading vertically as the bars a. close and overlap, asshown in Fig. 5. The fact that the bars ct are adapted by their peculiarform to overlap at their edges enables the gate to be closed intosmaller compass than has heretofore been possible.

In the form of gate shown in Figs. 2, 6, 7, and 8 the bars a aregroupedin pairs of the lazy-tongs pattern and are connected to similarvertical end bars ff. These bars are of the form heretofore described,and when the gate is closed the edges overlap, so that the bars arebrought closely together 'into compact form, occupying but little space.

In the construction and placing of the'gate, Figs. 1 and 2, the verticalright-hand bar is preferably movable and provided with a handle androller in the lower end and the lefthand bar rigidly or pivotally fixed,Aso that the bars composing the gate are moved up to or away from thesaid left-hand bar in opening or closing the gate.

Both forms of gate shown are well known, my in vention relatingparticularly to the form of` bar employed for the gate. These bars arelight in weight and stiff and rigid both length- Wise and crosswise, andbecause of these qualities a much smaller bar in cross-section can beemployed in a gate of given capacity' than would be possible in theusual flat-bar gate.

I claim as my invention- 1. A metal gate composed of pairs of parallelbars, each bar having two parallel longitu- IOO dinal -ribs upon onesurface at either sideof the center, `and 4spaced at substantially thesame distance from the edges that they are apart, the bars of the pairsbeing oppositely and alternately placed and adapted when closed tokoverlap at :the edges and-*pivotal devices for connecting the bars,snbstantially as set forth.

2. A metal gate composed of pairs of parallel bars, each bar having twoparallel Elongitndinal ribs upon one surface at either side of thecenter and spaced at substantially the same distance from the edges that-gthey are apart, said bars being so placed thatthe bars of one pair areconnected with their fiat faces turned inward and the bars of the nextpair with theirA rib-faces turned inward, \the several bars beingadapted when closed to over- .lap at :the edges, andineans forkconnecting the bars, substantially as set forth.

3. A metal gate composed of pairs of parallel bars, each bar having twoparallel lpngitn- `subsirmltially as set forth- Signed by me this 20thday of June, 1900. ACHILLE F. BATAILLE.
